wpa_supplicant and ral(4): RTM_IEEE80211: disassoc (102)

[Torsten Harenberg <harenberg%physik.uni-wuppertal.de@localhost>]

Dear list,

on my netbook, running NetBSD 5.0_STABLE/i386, I try to get an internal 
wireless card running which is a Ralink RT2790.

The ral(4) driver does not support it in STABLE, but there has been some efford 
going on to support this one [1], [2]. Finally, Quentin Garnier kindly prodived 
a patch which makes this card working (and he reports that it runs at least 
with WEP encyrption) [3].

WIth this patch, the card is properly recognized by the kernel:

th-akoya# dmesg | grep ral0
ral0 at pci2 dev 0 function 0: vendor 0x1814 product 0x0781 (rev. 0x00)
ral0: interrupting at ioapic0 pin 17
ral0: MAC/BBP RT2872 (rev 0x0200), RF RT2720 (1T2R)
ral0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
ral0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 
36Mbps 48Mbps 54Mbps

However, when trying to use wpa_supplicant with this card, the connection seems 
to be established but gets broken:

State: 4WAY_HANDSHAKE -> 4WAY_HANDSHAKE

I thought that it might be related to the patch from Quentin, but after 
searching a bit I found that another user has opened a PR [4] which seems to 
show exactly my problem, but he is using an USB based device which is supported 
by the ral(4) driver in 5.0 without any additional patch.

There has been a lenght thread already about a year ago on this list [5] and I 
applied the patch to wpa_supplicant given in [6] in the same thread. Finally 
there has been a pullup-request to the netbsd-5 branch, which has been applied 
[7]. 

Still, the problem exists at least here and also at the user submitting the PR 
[4]. I tried two networks (one at home and one commercially operated at my 
office), both show this problem.

I attached a full "-d" output of wpa_supplicant to the PR. 

Is there way to proceed from here?

Thanks a lot and best regards,

   Torsten
